Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to course of operators, including the dangers associated with the dealing with of a lethal, highly corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on website and the broader surroundings ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a critical safety element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential dangers
The HF alkylation course of poses numerous critical environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in solid metallic elements that can ultimately cut back the lifetime of pumps, valves and different gear and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations nice importance on the choice of material of forged elements, notably when it comes to the pump casing and impeller.
Designed for resistance against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next era pumps are features which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the environment, and lowering operational risks and the related costs to satisfy stringent environmental and well being and safety targets. Finally, there is steady monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and protection towards dry pump running (power control monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting systems, the latest magnetic drive sealless pump technology offers vital safety, value and operational advantages. เพรสเชอร์เกจดิจิตอล -user set up prices and simplified maintenance necessities, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
